im russian and i can say that even русский царист is dumb because its 2 adjectives, and царист is not even a word.
русский царь is adjective+noun, so they are connectable with eachother
im such a nerd
My username is Russian Tsarist, not Russian Tsar
A Tsar is a Russian monarch, a Tsarist is someone who supports them. In this case, Царист is also a noun.
